Abstract: |
Strain SiGe layer is as cavity quantum trap, and Si is as cavity potential barrier so as to form structure of dual potential barrier single quantum trap. Undoping SiGe, Si, SiGe, Si, SiGe layers and heavy doping P type Si layer are deposited on high doping P type Si substrate by using chemical vapor deposition or molecular beam epitaxy method so as to form the platform structure. Poles are formed on substrate and the platform. Obvious differential negative resistance phenomena are observed in testing of current voltage characteristic. The invention raises integrity and is compatible to technique in mainstream. |
